An erlenmeyer flask contains 25.00 ml of 0.500 m hcl before a titration is begun. how many moles of hydrogen ions are present in the flask at this time?
0.0125
12.5
20.0
50.0

= 0.0125 moles

Explanation:

Molarity is given by the formula;

Molarity = moles /Volume in L

Therefore;

Moles = Molarity × volume in L

          = 0.500 M × 0.025 L

          = 0.0125 moles
